In: Canada October 1, 1941 6 Claims.

This invention relates to cloth covered clearer rolls for spinningframes and other textile machines.

Objects It is a principal object of the invention to provide a structurefor a cloth covered clearer roll wherein in the cloth covering isaffived in such a way as to prevent wear.

It is a further object 01, the invention to provide a roll of thisnature including, in addition to the cloth covering, bearing surfacespermitting the roll to rotate in sliding contact with bearings.

With these and other objects in view, the invention embodies a rollincluding a cylindrical foundation or form on which the cloth is mountedand over the ends of which it is inturned and members cooperating withthe form to retain the ends of the cloth in their inturned position. Theroll may be provided with spaced apart collars'of a smoothwear-resistant material serving as friction-free journals on which theroll may rotate, against stationary bearings.

Drawing The invention will be better understood by' reference to theaccompanying drawing in which a preferred form is illustrated and inwhich:

Figure 1 is a fragmentary elevation of a clearer roll constructedaccording to this preferred form.

Figure 2 is a longitudinal cross section through the roll shown inFigure 1.

Referring in further detail to the drawing,

this roll is made up of a central tubular foundation section or form 9and similar end forms Hi. The central and end forms are connected byplugs ll. Each plug ll includes end portions of increased diameterforming annular shoulders [2 adapted to fit snugly in the ends of theforms 9 and ID, and midportions 13 of reduced diameter.

Two layers ,20 of cloth are mounted on the forms 9 and I0. The outerends 2| of the cloth 20 are tucked in about the ends of the forms It andheld in place by a mushroom-shaped plug 25. This plug includes a stem 26extending within the form H3 and engaging the ends 2| and a head 2'!bearing against the end of the forms It.

The ends 30 of the cloth adjacent each plug are also inturned over theends of the forms 9 and I and the top of the shoulder H2. The ends 30are held in place by a smooth-surfaced collar 35 encircling the narrowportion l3 which pinches the ends between it and the ends of the forms 9and I0 and the shoulders l2.

The collars '35 maybe of "any suitable smoothsurfaced and hard-wearingmaterial adapted for slidable contact with a bearing. The applicant hasfound lignum vitae particularly suitable. The collar 35 is usuallyformed in two semi-circular mating halveswhich are adhesively securedtogether at their abutting ends and to the surfaces ofthe plug [3.

When a bearing surface is not needed centrally on the roll, the collars35 may be dispensed with and merely the end structure, namely, the plugs25 used. In this case, the tubes Hi and cloth covering 20 run the fulllength of the roll and pegs of steel would be inserted in the plugs, toserve as trunnions for journalling the roll.

Operation In operation, the cloth covered roll, in the case of thepreferred form shown, runs with the collars 35 sliding on respectivebearings and the cloth portion in contact with the roll which it isdesigned to clear.

In the case of ordinary forms of roll in which the collars 35 areomitted, the roll will be held in contact by springs supporting the pegsin the ends. f

In a structure such as this, the ends of the circular braided cloth tubeareneatlytucked in and held in place so that they will not fray. Theclearer roll i thus more desirably covered than one covered in the usualway.

Method of construction According to a preferred construction, the clothcovering 20 is a braided tube of cotton or other siutable fabric,normally slightly oversize in respect to the diameter of the cylindricalform to which it is to be applied. This cotton tube is worked on to ametal cylinder of larger diameter than the clearer roll form on whichthe cloth is to be mounted, adhesive is applied to the form and thelatter slipped within the cylinder. The cylinder thus intervenes thecloth tube and the metal form.

The cylinder is slipped from between the tube and the form, leaving thetube on the form. The tube is then smoothed out from a central point.Its braided construction permits it to contract in the transversediameter as it lengthens, thus bringing it down in size to the externaldiameter of the form to which it is affixed by the adhesive.

The plugs and collars are then put into place to secure the ends on theform and the assembly placed to one side for the adhesive to set, thenfrom the spirit thereof or the scope of the claims,

and therefore the exact forms shown are to be taken as illustrative onlyand not in a limiting sense, it being desired that Only'SllChlimitations shall be placed thereon as may be imposed by the state ofthe prior art or are set forth in the ac companying claims.

' I claim:

1. A clearer roll for spinning frames, comprising, a plurality oftubular forms, a plug extend-;

ing between adjacent forms and spacing them apart, said plugs eachincluding an annular channel between the adjacent forms, said forms having a cloth covering, the ends of said covering projecting and beinginturned over the. ends of said forms, a smooth-surfaced collarencircling each-plug in the channel thereof constituting a journal forthe roll, said collar engagin said inturned ends between it and the endsof the respective forms.

2. A clearer roll for spinning frames comprising, a-tubular form, anintegral cloth cover mounted on said form and having its ends inturnedabout the ends of said form, a plug inserted in the end of said tubularform to engage the ends of said cover, said plug being substantiallymushroom-shaped, a stem portion on said plug extending within the formand engaging the ends of the cloth between it and the form, the headportion of said plug abutting the end of the roll and engaging theinturned ends of the cover between it and the end of the form.

3. A clearer roll, compris ng, a cylindrical form, a plurality ofannular channels in said form, a collar of hard bearing material in eachchannel constituting a journal adapted for sliding contact with abearing, textile material surfacing other portions of the form andhaving ends adjacent the collars, ends of the textile material beingengaged and held in place by thecollars, the textile-surfaced portionsbeing adapted to perform the clearing function.

4. A clearer roll, comprising, a plurality of tubular forms, a plugextending between the ends of adjacent forms and connecting themtogether, clearing material surfacing each form to constitute. clearingportions, smooth bearing material surfacing each plug to constituteannular journals adapted for sliding contact with stationary bearings,the bearing material abutting the ends of the clearing material andholding it in position, the surfaces of the bearing material being insetslightly from the surfaces of the clearing material thereby to form arelatively uniform diameter of the roll throughout its length.

5. A clearer roll, comprising, a plurality of tubular forms, a plugextending between the ends of adjacent forms and connecting themtogether, an annular channel in each plug, a collar of smooth bearingmaterial in each channel constituting an annular journal adapted forsliding contact with a fixed bearing, textile material surfacing theforms and projecting over the ends thereof to be engaged by saidcollars, said textile material also projecting over the free ends of theforms, means connected to the free ends of the forms for retaining theprojecting ends of the textile material.

6. An elongated clearer roll, comprising, a plurality of relativelyextensive clearing portions and a plurality of relatively narrow journalportions intervening said clearing portions, said journal portions beingspaced apart from each other and from the ends of the roll whereby, theclearer roll, is adapted to be journalled in termediate its ends, eachjournal portion being surfaced with smooth hard material inset slight-.ly from the surfaces of said clearing portion and constituting ajournal, the surfaces of said clearing portions being surfaced withclearing material, an end member on each end of said roll, the ends ofsaid clearing material abutting said journal and said end members andbeing held in place thereby, each end member having a continuous smoothsurface effective to inhibit the collection of fly.
